Why mail.ru and the Yandex mail application do not apply the background color?

Question

css

Hey! I typed up a letter, but for some reason in mail.ru and in Yandex the background color changes from the prescribed one to its own, dark one?
how to get around this in the layout of the letter?

Answer 1

1. E-mail layout = pain.
2. A little less pain if you type them in HTML4 Strict + standard inline styles.
3. Any letter receiver will easily put a bolt on your efforts.
